  • the oxidizing agent used is generally hydrogen peroxide.
  • the basifying agent makes it possible to adjust the pH of the composition to an alkaline pH to enable activation of the oxidizing agent.
  • this basifying agent causes swelling of the keratin fibre, with raising of the scales, which promotes the penetration of the oxidizing agent, and also of the dyes, if they are present, essentially oxidation dyes, into the fibre, and thus increases the efficacy of the dyeing or lightening reaction.
  • basifying agents and especially aqueous ammonia, have the drawback of causing the user discomfort due to their strong characteristic odour.

Description

Composition comprising (2,5-diaminophenyl)ethanol, an alkylpolyglucoside nonionic surfactant, an oxyethylenated sorbitan ester or a polyalkoxylated or polyglycerolated fatty alcohol in a medium rich in fatty substances, dyeing process and device
therefore
The present invention relates to a composition for dyeing keratin fibres, in particular human keratin fibres such as the hair, comprising a) one or more fatty substances, which are preferably non- silicone li qui ds, b) one or more alkylpolyglucoside nonionic surfactants, one or more oxyethylenated sorbitan esters, one or more (poly)alkoxylated alcohols and/or one or more (poly)glycerolated alcohols, c) (2,5 -diaminophenyl)ethanol and also acid salts thereof or solvates thereof, d) optionally one or more couplers, e) optionally one or more basifying agents, f) one or more chemical oxidizing agents such as hydrogen peroxide, and whose fatty substance content represents in total at least 20% by weight, particularly at least 25 % by weight, even more particularly at least 30% by weight, more preferentially at least 40% by weight and even more preferentially at least 50% by weight relative to the total weight of the composition.
The invention also relates to a dyeing process using the said composition, and to a multi-compartment device that is suitable for using the said dye composition.
The present invention relates to the field of dyeing keratin fibres and more particularly to the field of hair dyeing.
Many people have sought for a long time to modify the colour of their hair and in particular to mask their grey hair.
One of the dyeing methods is "permanent" or oxidation dyeing, which uses dyeing compositions containing oxidation dye precursors, generally known as oxidation bases. These oxidation bases are colourless or weakly coloured compounds which, in combination with oxidizing products, can give rise to coloured compounds by an oxidative condensation process . It is also known that the shades obtained with these oxidation bases may be varied by combining them with couplers or colouration modifiers, the latter being chosen especially from aromatic meta- diamines, meta-aminopheno ls, meta-diphenols and certain heterocyclic compounds such as indo le compounds. The variety of the mo lecules used as oxidation bases and couplers allows a rich palette of colours to be obtained.
It is also possible to use direct dyes in order especially to provide glints to the colouration obtained. These direct dyes are co loured and co louring mo lecules that have an affinity for the fibres . Examples that may be mentioned include nitrobenzene, anthraquinone, nitropyridine, azo, xanthene, acridine, azine and triarylmethane direct dyes.
Permanent dyeing processes thus consist in using, with the dye composition, an aqueous composition comprising at least one oxidizing agent, under alkaline pH conditions in the vast majority o f cases . The role of this oxidizing agent is, at least partly, to degrade the melanin o f the hair, which, depending on the nature of the oxidizing agent present, leads to more or less pronounced lightening of the fibres. The oxidizing agent used is generally hydrogen peroxide.
One of the difficulties encountered during the implementation of the dyeing processes of the prior art arises from the fact that they are carried out under alkaline conditions and that the basifying agents mo st commonly used are aqueous ammonia and amines. Specifically, the basifying agent makes it possible to adjust the pH of the composition to an alkaline pH to enable activation of the oxidizing agent. In addition, this basifying agent causes swelling of the keratin fibre, with raising of the scales, which promotes the penetration of the oxidizing agent, and also of the dyes, if they are present, essentially oxidation dyes, into the fibre, and thus increases the efficacy of the dyeing or lightening reaction.
However, these basifying agents, and especially aqueous ammonia, have the drawback of causing the user discomfort due to their strong characteristic odour. In particular, not only may the user be inconvenienced by the odour given off by these basifying agents, but also may be confronted with greater risks of intolerance, for instance irritation o f the scalp, which is especially reflected by stinging.
It is also important to obtain colourations that are satisfactorily light-fast. However, the use of certain couplers such as meta-phenylenediamines, for example, induces degradation caused by sunlight.
Moreover, it has been proposed in oxidation dyeing to use an oxidation base of (2,5 -diaminophenyl)ethanol type (EP 0 858 796) .
Co lorations that use this oxidation base are also known, especially combined with particular acids such as diethylenetriaminepenta(methylene)phosphonic acid (EP 2 103 299) or with chlorinated bases or chlorinated couplers such as 2-amino-6- chloro-4-nitrophenol, 2,6-dichloro-4-aminopheno l, 2-chloro-6- ethylamino-4-nitrophenol 3 -amino-5 -chloroaniline, 2-chloro-4- aminopheno l or 2-chloro-6-methyl-3 -aminopheno l (WO 98/ 17233 , WO 98/ 19658 , WO 98/ 19659, WO 98/ 19660, EP 0 985 406, EP 0 727 203 , DE 19828204 , DE 19724334 or WO 96/ 15765 ), or with couplers such as 3 -(2,4-diaminophenoxy)- l -propanol (WO 2001 /05 1 019) . However, these combinations of bases, couplers and acids produce colours that are not always satisfactory, whose dyeing power is limited or even insufficient to ensure in particular suitable coverage of grey hair and/or which show excessive selectivity of the co louration between the root and the end and/or insufficient fastness with respect to external attacking factors such as light, shampoos, inclement weather, etc. In addition, none o f these documents describes a dye composition comprising a large amount of fatty substances, in particular of oil.
One o f the obj ects of the present invention is thus to propose compositions for dyeing human keratin fibres such as the hair, which do not have the drawbacks of the existing compositions.
In particular, the composition according to the invention in the presence o f a chemical oxidizing agent makes it possible to obtain co lours that are satisfactory, especially in terms of power in general, but also with sufficient coverage or build-up of the colour at the root o f the hair, which makes it possible to avoid a "root" effect of the co louration. The colourations obtained are also sparingly selective . Finally, it is also possible to obtain colours that are very light- fast.
Furthermore, the invention makes it possible to achieve substantial degrees of lightening while at the same time colouring, without using persalts or increasing the amount of chemical oxidizing agent or of basifying agent.
These aims and others are achieved by the present invention, one subj ect of which is thus a cosmetic composition for dyeing keratin fibres , in particular human keratin fibres such as the hair, comprising : a) one or more fatty substances ;
b) one or more alkyl(poly)gluco side nonionic surfactants and/or one or more oxyethylenated Cs to C30 fatty acid ester(s) of sorbitan and/or one or more (poly)alko xylated alco ho ls and/or one or more (poly)glycerolated alcohols ;
c) one or more oxidation base(s) cho sen from (2 , 5 - diaminophenyl)ethanol, and also acid salts thereo f or so lvates thereo f such as hydrates;
d) optionally one or more coup ler(s) ;
e) optionally one or more basifying agent(s) ;
f) one or more chemical oxidizing agent(s); and
the fatty substance content representing in total at least 20% by weight relative to the total weight of the composition, preferab ly at least 25 % by weight, more preferably at least 30% by weight, better still at least 40% by weight and even better still at least 50% by weight, relative to the total weight o f the composition.
A subj ect of the present invention is also a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, in which the dye composition according to the invention is applied to the said fibres .
The invention also relates to a multi-comp artment device for using the composition according to the invention. Thus, the use o f the dye composition according to the invention leads to powerful, intense, chromatic and/or sparingly selective co lourations, i. e. co lourations that are uniform along the fibre.
The dyeing process of the invention also makes it possible to cover keratin fibres particularly well at their root, especially down to three centimetres from the base of the said fibres. Moreover, the co lours obtained after treating the fibres remain stable, in particular with respect to light.
The invention also makes it possible to reduce the amounts of active agents o f the invention such as the dyes and/or basifying agents and/or oxidizing agents.
Moreover, the process according to the invention makes it possible to use compositions that are less malodorous when they are applied to the hair or being prepared.
Other characteristics and advantages of the invention will emerge more clearly on reading the description and the examples that fo llow.
In the text herein below, and unless otherwise indicated, the limits o f a range o f values are included in that range.

Dyeing device Finally, the invention relates to a first multi-compartment device comprising a first compartment containing composition (A) as described above and at least a second compartment containing composition (B) as described above, the compositions o f the compartments being intended to be mixed before application to give the formulation after mixing according to the invention, provided that the amount of fatty substance in this formulation represents at least 20% by weight, preferably at least 25 % by weight, more preferably at least 30%) by weight, better still at least 40%> by weight and even better still at least 50% by weight, relative to the total weight o f the formulation resulting from the mixing o f (A)+(B) .
The invention also relates to a second multi-compartment device comprising a first compartment containing composition (Α ' ) as described above and a second compartment containing a cosmetic composition (Β ') as described above and at least a third compartment comprising composition (C) as described above, the compositions of the compartments being intended to be mixed before application to give the formulation after mixing according to the invention, provided that the amount of fatty substance in this formulation represents at least 20%) by weight, preferably at least 25 % by weight, more preferably at least 30%> by weight, better still at least 40%> by weight and even better still at least 50% by weight relative to the weight o f the formulation resulting from the mixing of (A' )+(B ' )+(C) .
The examples that follow serve to illustrate the invention without, however, being limiting in nature.
The evaluation o f the co loration can be done visually or read on a spectrocolorimeter (such as Mino lta CM3600d, illuminant D65 , angle 10° , SCI values) for the L* , a* , b * colorimetric measurements . In this L * , a* , b * system, L* represents the intensity o f the co lor, a* indicates the green/red color axis and b * indicates the blue/yellow color axis . The lower the value of L, the darker or more intense the color. The higher the value o f a* , the redder the shade; the higher the value of b * , the yellower the shade. The variation in co loring between the co lored locks of natural white hair (NW) which is untreated (control) and after treatment or coloration are defined by ΔΕ * , corresponding to the colour uptake on keratin fibers, according to the fo llowing equation:
Figure imgf000059_0001
In this equation, L*, a* and b* represent the values measured after dyeing the natural hair comprising 90% of white hairs and Lo*, ao* and bo* represent the values measured for the untreated natural hair comprising 90% of white hairs.
The greater the value of ΔΕ, the greater the difference in color between the control locks and the dyed locks and the greater colour uptake is.
On the other hand for evaluating the selectivity of the color between the root and tip of the keratin fiber, measurement can be done on permed or sensibilised white hair (PW) and natural white hair, wherein the variation in coloring between the colored locks PW and the colored natural white hair are defined by ΔΕ*, corresponding to the selectivity of the colour, is calculated according to the following equation:
Figure imgf000059_0002
In this equation, L*, a* and b* represent the values measured after dyeing the natural hair comprising 90% of white hairs and Lo*, ao* and bo* represent the values measured after dyeing the permed or sensibilised hair. The lowest ΔΕ*, the best homogeneity of the hair color.
If the light fastness is investigated, ΔΕ* is also calculated for the L0*, a0*, bo* and L*, a*, b* measured of the locks before and after exposure to the light, respectively.
Chromaticity in the CIE L*, a*, b* colorimetric system is calculated according to the following equation :
Figure imgf000059_0003
The greater the value of C*, the greater the chromaticity is. The examples that follow serve to illustrate the invention without, however, being limiting in nature. Example 1
